The decision of the Board of Control for Cricket in India (BCCI) follows January's meeting with a Cricket Australia delegation led by chairman Earl Eddings.
Australia have pushed for more pink-ball Tests, which are favourably timed for spectators and TV audiences as they continue into the evening, as they host India in a four-match series in December-January.
"Day-night Test will happen and we will make a public announcement -- the second Test against England next year. Yes, against Australia also," Ganguly told reporters after a board meeting in New Delhi on Sunday.
India will host England in January-February 2021 for five Tests, of which one will be under lights -- and possibly at the refurbished stadium in Ahmedabad, which will be the world's biggest cricket venue when it opens.
Virat Kohli's India played their first day-night Test in Kolkata last year, thrashing Bangladesh in just over two days.
Earlier India had declined Australia's offer of playing a pink-ball Test in Adelaide at the end of 2018, but Kohli now appears more at ease with the format.
"We played the day-night Test here and were pretty happy with how it went. It's become a very exciting feature of any Test series, so we are absolutely open to play a day-night Test," Kohli said in January.
